Elastic disk stats not correct with Kubernetes local storage

I'm running Elasticsearch in a Docker container in Kubernetes with local storage. Elastic only sees an overlay mount, which is at the root. It doesn't see the local storage mount. And so it's not reporting the correct amount of storage available and it's causing issues with shard allocation and watermark alerting. Has anyone else run into this issue?

  Filesystem               Type       Size          Mounted on 
  overlay                  overlay    500G          /
  /dev/disk-disk           xfs        2T            /data

Elastic only sees the overlay and therefore only sees 500G as opposed to 2T

Nevermind. I need to set my /data path.
